, the free circulation of the air, except Where Patented Sept. 29, 1914. Renewed February 24', 1914. 'serial No. 820,660.

tion is a rotary fan 8 of the ordinary c0nstruction, mounted on 'a horizontal shaft 9 which is the driving shaft of the drier in the present instance, so that when the fan shaft is driven it circulates the air in the direction of the arrows around the partition The upper portion of the drier is rounded so that there is no obstruction for opening 6. In an opening 7 in the partiit passes through the openings in the partition.

In order to heat the air as it circulates in the drying chamber, We mount a series of steam coils 10 in the chamber and support them by'a frame 11 which is secured to the angle plate 12 to which the upper 'end oi the partition 5 is attached, and the lower end oi' this frame is secured'to the front wall of the drying chamber, as illustrated in Fig. el. Cross bars l'support the pipes', es clearly shown in said figure. The steam coil l0 is connected to a steam supply ypipe 18, :unli is a gage connected to the pipe so that the amountof pressure can be readily :ist rtained and the steam controlled aceordingly. At each end of the drier are doors li which are hinged, as shown1 and between the doors and the front Wall l5 of the drier are slots 16 and 17 of a Width which allow the passage of a stocking form with a stocking thereon.

Arranged to travel in the guideway 2 are carrier. 20, and pivoted on the head 2l of ouch carrier is a bracket 22 having a spindle arranged to extend through the bear- 'i fj on the head 2l. On the outer end of ilus spindle is an arm 23 having two rollers and 25. rllhe roller 24 is adapted to a 'ail 2F secured to the table and running iraliel with the guideway at the back and one side of the bed, as clearly shown in rlhis roller also travels on a right red rail 27 extending parallel with the gunlen'zv at the frontof the table and at 10G the apposite end, as clearly illustrated in said sure. The other roller 25 travels over a plate 28, when the stocking form. emerges from the drier and is'loWered by this cani plate, in the present instance to the hor' tal position to allow for the removal o :i stocking from the form; the forni resting;- on the support 29 during this The stockings may he removed n the forms by hand or by automatic shown any automatic means for removing a stocking from a form, but said automatic l, be dis ensed With.,

-jvtialg features of the invention. The form'ismeans is fully set forth and claimed in a companion application filed on the 14th day of May, 1913, under Serial No. 767,649.

'It willbe understood that the Vstocking can be removed from the form by hand after the form has'beeIL turned t'o the horizontal position, and when it is desired, to remove a stocking Without turning .the form, -the roller 25, cam plate 28 andsupport 29 can -In t e present instance the stocking form 30.is made'of metal, but it Will be understood that it may be made of Wood, or other material,.without departing from the essendeta'ohablysecured to aclamp head 31 havinge, spindle 32 which extends at an angle through a bearingl in the bracket 22.' A counterweight 33 is used to hold the form 30 4in anupright position, but this counter- Weight is onlyvused when the' form is so pivoted to thecarrier .that it can bemoved from the vertical to the horizontal position. The s indle 32 is narrow and extends throng a slot-34 on the bottom plate'35 of the overhanging portion 4 of the drier, so

' through' the slot.

that comparatively little hot. air escapes -iiiechanism of the -carrier which requires lubrication is Aon the outside of the drier and is not subjected directlyto the circulating hot air.

The carriersare traversed in the guide- Ways in the present'instance, by mechanism broadly setV for'ith'and claimed-,in a patent granted' to us on February 25th,l 1,913, No. 1,054,459, and ythis inechamsmfis slightly modifiedv to.' '.nccomnodate the particular cons'tructioln. vof this machine, This construction wewill now proceed to describe.

TheA fan shaft 9 is the dri/ving'v shaft in the present instance', and has cone pulley 3611.1, one end around which passes a belt 37 whichv also passes around a 'cone pulley 3 8 on a stud 39. A

40 is a shifter 4rod and this shifter rod has a -forkedijarni'43 engaging the belt 37. The study 39 i mounted on an arm 44,'a djustalolev on the f'rame 42,- so that, by turning the armfon tlieframe,

the slack of the belt can be taken'fup; j OnV By this construction the mounted [in beari gs` L-lfl ina bracket dependingv from a f ame 42,

in the present instance,iso that-the shaft canbe thrown into and out ofgear by the said rod 53.

67 is a treadle shaft mounted on Vthe floor in the present instance, and yon this shaft is an arm 68 which engages the .rod 5.3, 'so that, if desired, 4the clutchsleeve ycan be moved in'to and out ofl engagement with' the Worm 'wlieel by 'actuating the treadle shaft by the foot. The shaft 50 extends are cams 54 and 54, as illustrated in-Fignf The cams engage a pi'n' 55 on the underside of each carrier 2 0.:y The pins are preferably..` Y pro-videdwith rollers so that the cams will` the machine. and this shaft is geared, in the y present instance, to the shafts 56 and 5,8 by vbevel gearin Y61 'and 62, respectively. On the shaft 60 is acam 63 which traverses the carriers through the guideway'at the front of themachine. During portion of the sof travel of the carrier, the form is removed fromthe stockingv and during the balance of the movement another stocking is placed upon the form.A

When the carrier reaches the end ofthe frame it leaves thecam 63 Aand is engagedby a cam 64 on the shaft 56 which carries .v the form, with the stocking thereon, through.

the slot 16 in the drier 3 and, after the'form is entirely Within the drier, it is engaged by the cam 54 Whichtraverses it longitudinall in the drier for a certaln distance and until it comes in contactwith a preceding carrier,

thedrier a given length; of time', and, by

`allowing the carriers' tocome'. in contact with each other and to push one another through the drier,` a comparativelyishort, rier may be used for a large number ofl orms. "i

.Tflhen the carrier reaches the endl-.of the` longitudinal inner. guideway, a cam 65 onv 'the shaft l58 engages the-pin of the'carrier,4

and removes the stocking form from the Vdrier through the slot 17. This cam traverses the carrieruntil it is again engaged'by the lirst mentioned cam 63. VThis carrier is moved in a continuous path. On one end of the cam 54 is an arrow head shapedso as to enter the space betWeentWo carriers and thus separate them, as We have vfound that the carriers are liable to Stick together due '66 is a cam mounted on the shaft 58 which extends parallel with a portion of the cam 65 and isfor the purpose of controlling the iisl 7D along the rear of the bed and 0n Avthe .Shaft v 1.25v to' the lubricating oil getting on the adjoin-e/ 'ing' surfaces.

movement of the carrier, While the form is being,r turned from the vertical to the horizontal position, as the carrier has a tendencyv to move faster than the cam (35 at this point.

.in Order to clningre the stocking' form trom the horizontal to the vertical position, While traversing vin the front longitudinal guideway, the end 69 of the rail 2T is so arranged that it forms an abutment for the roller 2l on the arm of the bracket carrying the stocking form, so that, when the roller cornes in Contact With this abutment, it ivill turn the stocking form on its pivot and vvill roll onto the rail 27. `A cam plate T0 is located in the path of lthe stoclring''orm so that; as it is raised from the horizontal to the vertical position, one edge of the form comes in contact With this cani plate TO and turns it on its pivot, thus the side of the stocking' form will be presented to the operator as this is the best position for the operator to place a stocking on the form. The form can be freely turned on its pivot to enable the operator to see that a stocking is properly placed on the4 form.

ln order toprevent t "cidentally on their pi through the drier, spindle 32 of each in the narrow slot by side.

From the above description, it is obvious that the construction of the drier is such that, when the forms, with the stockings thereon, extend into the drying chamber, the carriers and the mechanism for driving the carriers are outside of the chamber and are protected from the heat. Furthermore, all of the mechanism is accessible.

The operation is follows: The operator stands in frontof the'niachine toward one side and, as the stocking form is raised from the horizontal to the vertical. position, a stocking is lnlaced upon the form by the operntor While it moves slowly past him. The stocking form is so controlled that when it traverses the first transverse guide it will enter the drying chamber through the narrow slot 1G with the toe portion of the stocking in advance, and, when the torin is enti within the drier. it is traversed ioni; nally thereof until it emerges from the hier through thJ slot 1T. Then, as the carrier traverses the other transverse gnidewan, the forni turned on its pivot to the hor ntal position` it desired, and the stocking is removed Jfrom the forni either by` hand or bv the automatic mechanism mentioned above. As the carrier travels in the `guideivay at the front of the n'xuchine the stocking' form assumo: a vertical lposition in readiness for an otl1erntoolring to he placed thereon.
